Abstract
The invention relates to a device for dynamic measurement of the surface tension of a liquid by the bubble pressure process. The device is characterized by a moving measuring device with a flexible lead, conveying at least compressed air, to a sensor head which releases bubbles and can be immersed in the measuring liquid. The moving measuring device has an input keyboard for different operating modes, a display for monitoring the measuring modes and display of the measurement results, a volume flow source for generating the gas pressure, a pressure sensor for detecting the quality of gaseous bubbles, a microprocessor for measuring and evaluating the measurement results and an internal current supply for all power consumers.
